Create Sub-tasks when an Issue is Created


This script automatically creates sub-tasks when a new issue is created.


I require a set of sub-tasks to be added to each new issue I create. Usually, I have to create these sub-tasks manually, which is time consuming. Using this script I can automate the process, creating sub-tasks for each new issue without the need for manual configuration.

Good to Know

  • This script can bet set as a listener for Issue Created event.
  • This script is not executed when sub-tasks are created.
  • Sub-tasks are added to a particular issue with the same type as parent issue.
